- For L-Band Pulsed Radar Application
• Easy To Use – 50 Ω Plug-and-Play
• Reduce Design Cycle Time
• Improve System Performance
• Reduce System Size and Components
GENERAL DESCRIPTION
The 1214-550P is a 50 ohm matched Power Solution Module (PSM) for L-Band pulsed Radar systems
capable of providing 550 Watts of pulsed RF output power at three hundreds microsecond pulse width
ten percent duty factor across the band 1200-1400 MHz. This PSM designed with plug-and-play
concept which is extremely user friendly and requires no additional tuning and impedance matching
from the customer. Mechanical Size is 3.2” x 2” x 0.25”
